`S1?ECIFICATION' forming part of Letters Patent No. 283,180, datedAugust 14, 1883. Application med May 21, rees. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM E. WILD, of

` `the city and county of San Francisco, State of California, haveinvented an Improved Ore- Feeder; and I hereby declare the following tobe a full, clear, and exact description thereof.

The object of my invention is to feed ore to lthe battery with accuracyan'd in quantities regulated according to the wants ofthe stamp.

Referring to the accompanying drawings, Figure l-is a perspective'viewy'of my ore- Fig. 2 is a vertical section taken through the center fromfront to rear. Fig. 3

Fig. 2 with the feeding mechanism removed. 7

A is a standor frame, between the front standards of which is supportedupon a cross- I `the rear of the tray, and a cross-rib, d, on its c, isput in the partition,

beam, a, a tray, B.

D is a hopper supported Within the stand. I

The lower edge of itsrear wall extends within back, rests upon the rearedge of the tray, and its sides rest upon the sides of the tray. Vithinthe hopper is apartition, O. This consists of two plates, converging tothe top, thus dividing the hopper into two compartments,

which narrow to the bottom. The rear edges of the partition extend tothe lower edge of the rear wall of the hopper, but its forward edgesextend only to the base of the frontwall of the hopper, which terminatesshort of the upper edges of the tray. To do this, the lower edges ofthepartition are cutaway at c, thus forming passages oneach side for theore to pass fromthe hopper to the center ofthe tray. A guard-wall, justback of its front. The partitionG is open in front, and the front 1wallof the hopper is also cut, forming an opening, cl. All these partsmay be constructed separately and fitted together in any them, the trayand the partition may be made integral or secured together and thehopper.

; slipped or fitted down to"` its place by having projecting in front ofthe stand A. This edge .is rounded, and its` center is cut out at b,thus forming an opening at that point and leaving p on each side whatmay be termed lips b.

Pivoted upon one side of the stand A is a long lever, H, with one end ofwhich is connected a rod, I. The lower end of this rod is connected by alink or arm, J, with the rear standard of frame A. It has also pivotedto its lower end a bar, K, `the forward end of which is pivoted to thefriction-arm Il. This friction-arm is pivoted in the lower ends ofhangers M, mounted above upon shaft E. It

consists of a heavy bar pivoted near its rear end, in order that, lbyreason of the weight of its forward end, its upper surface maybe held`in impingement with the friction-pulley. The

weight of therod I, arm J, and bar K is suffi/- cient to maintain .theforward end of the lever H in an elevated position.

N is the tappetirod. I This is fitted to the j forward end of the leverthrough an elongated slot, 7L, therein, whereby it may be adjusted toany proper position to be struck by theV tappet. This is renderednecessary by reason of the gradual working out of position of the standA and the constant care required to adjust -it with such nicety that thetappet shall always strike the tappet-rod. By being mounted in the sloth the upper'end; of the'rod may `be kept in position, notwithstandingthat the whole feeder may move from its place. When `the tappet Tof the,stamp-stem S in descending strikes the tappet-rodN,- it forces down theforward end of lever H, raising rod I, which,

by reason of its connection with arm J, forces forward and upwardthe barK. This upward movement of bar K tends to hold the frictionarm L closelyagainst friction-pulley G, and its forward movement rotates said pulley,

which revolves shaft-E and causes the feederarms f to move inward aboveand outward below over the bottom ofthe tray, thus scraping or pushingwhatever may be in the trayforward over the edge of its opening Z1. WhenIOO ICI

within the hopper all clogging ofthe ore in its' throat is prevented.The ore works down the sides of the tray and reaches the feederarms fromeach side. These, by revolving in the partition, encounter no ore behindthem, but only when they move down to and scrape over the bottom of thetray. They are therefore not impeded in their forward. movement, andwill feed the ore forward through opening b without becoming clogged.The raised side lips, b, of the tray prevent the ore from falling out.They direct it down to the bottom, to subject it to the action of thearms f.. If there were no partition in the hopper, and the ore wereallowed to gravitate to the tray over its entire surface, the arms wouldnot be able to revolve, but would bind-against the mass from the rear,which would-soon clog in the throat of the hopper and in the tray; butin my feeder the ore is allowed to fall into the tray from each side,and it does not interfere with the arms, as these are protected withinthe partition. It is therefore pushed forward from the bottom of thetray without trouble.

Having thus described my invention,what I claim as new, and desire tosecure by Letters Patent, is-

l. In an ore-feeder, the dish-shaped tray B and the rotating feeder-armsf, in combination with the hopper D and a means for directing the oreinto the tray on each side of the feederarms, substantially as and forthe purpose herein described.

2. In an ore-feeder, the dish-sha] ed tray B 'and the rotatingfeeder-arms f, in combination with the hopper D and the centralpartition, C, within the hopper, said partition being constructed with awide base and open front to direct the ore into the tray upon the sidesof the feeder-armsand to protect said arms, substantially as hereindescribed.

3. In an ore-feeder, the dish-shaped tray B, having a front opening, b,and the rotating feeder-arms f, mounted over said tray, in combinationwith the hopper D, having a front opening, d', and the-partition C,having sloping sides, a wide base, open front, and side openings, c, todirect the ore into the tray'on each side of the feeder-arms, allarranged substantially as herein described.

4. In an ore-feeder, an ore-tray, in combination with a revolvingfeeding device, the friction-pulley G, the lever H, means foroscillating it, the rod I, arm J, bar K, the weighted friction-arm L,and the hangers M, as herein described.

5. In `an ore-feeder, the hopperD and the ore-tray B, in combinationwith the shaft E,

hub F, feeder-arms f, tappet T, tappet-rod N,

leverH, rod I, arm J, bar K, weighted friction-arm L, andfriction-pulley G, all arranged and operating substantially as hereinde- 7o scribed.

6. In an ore-feeder, an ore-receptacle, a feeding device, intermediateoperating devices, and lever II, having an elongated slot,

h, in its forward end, in combination with the 7 5 tappet-rod N, fittedloosely in said slot, and the tappet T of the stamp, substantially asand for4 the purpose herein described.

In witness whereof I hereunto set my hand.
